ACLU lawsuit accuses police of attacking Portland volunteer medics

"Volunteer medics should be celebrated, not attacked or arrested."

The big picture: It's the latest lawsuit filed in connection with officers' response to the demonstrations in Portland.

• The ACLU has also filed a suit against the City of Portland and the Trump administration on behalf of journalists and legal observers the group alleges were attacked by police while covering the protests. A motion to add federal agents to that order is pending before the court, with arguments scheduled for Thursday.
• On Wednesday, a federal judge heard arguments in a lawsuit filed by Oregon Attorney General Ellen Rosenblum, who accused federal agents of unlawful tactics following reports that some in unmarked vehicles detained Portland protesters without explanation, per AP. The suit seeks a restraining order against such action.

The other side: The Trump administration and City of Portland did not immediately respond to Axios' requests for comment.

• However, Acting Homeland Security Secretary Chad Wolf said Tuesday federal agents "will not retreat" from Portland. "The smear attacks leveled against our officers is disgusting," he said.
